Please help Edgar measures the temperature of a solution at the beginning of an experiment to be 23°F. He monitors the temperature of the solution every minute for 10 minutes. He records the change in temperature from his previous reading. His data show a decrease of 2 F four times, a decrease of 3 F three times, no temperature change two times, and an increase of 6 F once. (a) Write an expression that represents the average change in temperature each minute. (b) Edgar repeats the experiment and finds the average change in temperature each minute is 1F greater in the second trial than in the first trial. What is the average change in temperature each minute in the second trial of the experiment? Show your work.

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
